2932.93.00.00 - Piperonal (heliotropin)

This HTS category, 2932.93.00.00, specifically covers Piperonal, also known commercially as heliotropin. Piperonal is an aromatic aldehyde with a distinctive sweet, floral scent, reminiscent of heliotrope flowers and vanilla. It is primarily used as a fragrance ingredient in perfumes and soaps, as well as a flavoring agent in food products. Its characteristic aroma and chemical structure place it within the broader group of heterocyclic compounds containing only oxygen heteroatoms.

Within the "Other" subcategory of heterocyclic compounds, 2932.93.00.00 is distinct from its sibling entries based on its specific chemical identity. For instance, it differs from isosafrole (2932.91.00.00) and safrole (2932.94.00.00), which are related but have different functional groups and applications. Similarly, it is distinguished from 1-(1,3-Benzodioxol-5-yl)propan-2-one (2932.92.00.00), which is a ketone derivative. The classification hinges on the precise molecular structure and the presence of the aldehyde group in piperonal, as opposed to the olefinic or ketonic structures of its near relatives.

As a leaf node, this HTS code does not have further subcategories. Classification within 2932.93.00.00 is therefore determined by the definitive identification of the substance as Piperonal (heliotropin). Importers and exporters must ensure that the product meets the chemical specifications and purity standards associated with this designation to ensure accurate customs declarations.
